.T0 all wltmn it vmay concern:

Beit known th-at I, JOHN A. BRILL, a citizen of the United States, residing at Philadelphia,y in the county of Philadelphia and State 'of p Pennsylvania, have invented certain new and useful Improvements in Clutch or Clamp Tngs, ot' which the following isa specification.

My invention has relation to clutch or clamping tugs for ropes,traces,or other articles; and it has t'or `its object to provide an inexpensive, durable, and strong clutch or clamp tug which can be easily and quickly coupled to and uncoupled from the rope.

My invention accordingly consists of the combination,constructiomand arrangement of parts, as hereinafter described and claimed,

reference being had, to the accompanying drawings, whereinf Figure l represents asectional elevation ofa tug embodying my improvements; Fig. 2, an elevation of same, showing a rope clutched or clamped thereto; Fig. 3, an elevation of Fig. l from another pointof View, and Fig. i an end View of preferable form of sliding sleeve for the clutch or clamping jaws of the tug.

A represents a tug composed of almiddle plate, a, having at one end a hook, b, andat the other end two semi-tubular elongated jaws or clamps, c c, all of which are integral.' The plate ais preferably a :dat thin plate, having an oval outline in width, as shown, and is so arranged relatively to the hook and clamps that it aligns with the base of the hook and one side of the clamps, or, in other words, the hook and clamps project laterally from one side only of plate a, as shownfmore plainly in Fig. 3, to give the necessary space a between the rear end `of the clamps c c and the hook b,

to admit of coupling the hook` to and uncoupling it from a fixture, and also to avoid corners or projecting angles on both sides of. platea. The clamps c c are rendered lflexible `or slightly elastic by' forming the oppositely-lon cated slots c' between them.

The bore of the clamps c cis serrated or oth-L erwise roughened or formed into transverse ridges c2. Normally these clamps'c c diverge from one anotherfrom their hase or connection c3 with plate a, las indicated by dotted lines x, Fig. 1, and are drawn together by an exterior sliding sleeve, G, thereon. rIhis sleeveis preferabl y segmentally or poly'gonally made, as in.

dicated by full lines, Fig. 4, so that its inner The ,tug is made of malleable iron or other` suitable metal, and the hook b, platea, and the semi-tubular parallel clamps c c are all integral, so that they require no nishing, and all joints, pivots, and like fixtures are dispensed f A tug, A, composed of central plate, a, hav- ,Y n
